x%5E2%2B3x-1=0
Use Quadratic Formula: x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
ax%5E2%2Bbx%2Bc+=+0
x%5E2%2B3x-1=0, a = 1, b = 3, c = -1
x+=+%28-3+%2B-+sqrt%28+3%5E2-4%2A1%2A-1+%29%29%2F%282%2A1%29+
x+=+%28-3+%2B-+sqrt%28+9%2B4+%29%29%2F%282%29
x+=+%28-3+%2B-+sqrt%2813%29%29%2F%282%29
x+=+-3%2F2+%2B-+sqrt%2813%29%2F2

You got it correct
